Males typically have thicker ossicones that become bald on top due to frequent necking. [4] In okapi, the male's ossicones are smaller in proportion to the head, and taper towards their tips, forming a sharper point than the comparatively blunt giraffe ossicone. Whereas female giraffes have reduced ossicones, female okapi lack ossicones entirely.
The coat patterns of modern giraffes may also have coincided with these habitat changes. Asian giraffes are hypothesised to have had more okapi-like colourations. [6] The giraffe genome is around 2.9 billion base pairs in length, compared to the 3.3 billion base pairs of the okapi. Of the proteins in giraffe and okapi genes, 19.4% are identical.
Often mistaken with the southern giraffe, the northern giraffe differs by the shape and size of the two distinctive horn-like protuberances known as ossicones on its forehead; they are longer and larger than those of southern giraffe. Male northern giraffes have a third cylindrical ossicone in the center of the head just above the eyes, ranging ...

There are around 2,300 individuals living in the wild. [6] In the wild, female Kordofan giraffes live in loose groups, whilst males live solitary. [4] They have an average lifespan of around 35 years ...
